Author productivity and Erdoes distances in co-authorship and in web link networks

摘要

The increasing scientific-political importance of cooperation in sdencerequires the application of new methods of analysis of social networks inco-authorship and in Web link networks. In this context, some interesting papers on "Erdoes Number" which gives the shortest way (topological distance) between an author and the well-known Hungarian mathematician Erdoes in co-authorship network have been published recently. A few new queries which particularly concern the position of nighty productive authors in the network were developed in the present paper. Thus, a relationship of distribution of these authors among the clusters in the co-authorship network could be proved in dependence on the size of these clusters. Highly productive authors have on an average low Erdoes Numbers and thus shorter distances to an the other authors of a special field than low productive authors whereby the influencing possibility of highly productive scientists gets expressed among others in the development of this special field. A theory on the stratification in science with respect to the over random similarity of the scientists who are collaborating with one another which could be covered with other empirical methods before could also be confirmed on application of the Erdoes Numbers. The application of the new developed queries also on the web links between homepages of authors is proposed for studies in future. It has to be studied if co-authorship and web link networks have similar structures or not regarding the author productivity and Erdoes Distances.
